City of Ashes (Mortal Instruments #2) by Cassandra Clare
City of Ashes picks up not long after City of Bones ends. Clary and co. are dealing with the aftermath of events from the first book and with Valentine’s new plans for the world. There’s a lot of good development for the main characters and we get a lot more insight into everyone’s motivations and pasts.
I’m really looking forward to the next installment of this trilogy. It’s a really compelling series and I think the last book should be excellent.
